Dumbledore? He knows nothing about MC alchemy.

"Where is Kaisen today? You know, he is usually the most active in eating when he has nothing to do." Dumbledore asked.

"You said it too, it's a time when nothing is wrong." Snape responded.

"What's going on with him today?" Dumbledore asked.

The next moment, the whole hall shook horribly. Dumbledore frowned, and then he saw through the glass at the edge of the hall the base of a moving tower.

"Hiss...Professor McGonagall, look, is that the base of Gryffindor Tower?" he asked.

Professor McGonagall on the other side also took a look, and instantly, like the protagonist in the screaming oil painting, she held her face with both hands and shouted, "Kasen! What did he do!"

The others also saw from the window that thing that kept moving in the sky, as if it was looking for a place in mid-air...

"What the hell is that?" Ron asked confusedly while lying on the windowsill.

"It looks like... your tower has stood up." A girl in Beauxbatons uniform leaned against the window and said curiously.

"Oh, of course I can tell... My name is Ron Weasley, what's yours?" Ron was about to complain subconsciously as he did when talking to everyone else, but when he saw the person who had just spoken, he quickly changed his words.

"............You can call me Delacour." Fleur Delacour said.

"Oh, is that your name?"

"That's my last name."

"Oh well, I think your name is Fleur, right?" Ron started to chat awkwardly.

"........."

"Um, why aren't you talking?"

"........."

On the other side, Kaisen used a mechanical arm to fix himself on the outer wall of Gryffindor Tower. While controlling the remote control in his hand, he looked at the ground and slowly controlled the foundation to slowly fall into the original big pit.

boom!

Another sound, Dumbledore took a deep breath, and he suddenly regretted agreeing to that troublesome plan.

On the other side, Karkaroff came over quietly: "Dumbledore, what is Professor Kaysen doing now? Isn't it to intimidate us?"

Dumbledore glanced at Karkaroff and clicked his tongue. The meaning was very clear: Are you worthy?

Karkaroff returned to his students in disappointment and happened to meet Krum.

"Krum, you will be studying with Hogwarts students for most of this semester, right?"

Krum nodded. "That's right."

"That's good. Study alchemy well, and don't be afraid of losing face if you don't understand something. Just ask." Karkaroff patted Krum's shoulder and said.

"Ah."

On the other side, after seven or eight attempts, Kaisen finally succeeded in putting the foundation back into the poor big pit.

"It's finally over." Kaisen wiped the sweat from his forehead and breathed a sigh of relief after returning to the ground.

And waiting for him was Professor McGonagall, who had been waiting for him with her arms around his shoulders.

Seeing this, Kaisen subconsciously shuddered and quickly leaned next to Professor McGonagall: "Professor, you know our plan. You approved this plan at the time!"

Professor McGonagall gave Kaisen a strange look and said, "I'm not here to accuse you. I'm here to inquire about your transformation progress."

"..........So you're not rushing for the lesson plan anymore, you're rushing for this now, right?"

Chapter 267: Special Training to Level Up

"Progress...half of one leg completed?"

"Oh......." Professor McGonagall's sudden interest suddenly dropped: "I thought it was finished."

"How could it be so fast?" Kaisen shook his head with a wry smile.

"Okay... by the way, this matter may be difficult for you, but I still want you to try not to make too much noise if conditions permit." Professor McGonagall said tactfully.

"No problem, promise."

After completing Professor McGonagall's lecturing task, Kaisen casually began to sweep the dining table.

"How long has it been since you last ate?" Snape asked.

"Most of the day, mainly because... I consumed a lot." Kaisen rarely stopped chewing and answered after he had swallowed all the food.

Snape sighed and pushed a glass of pumpkin juice over.

"Oh, thank you!"

Kaisen took the pumpkin juice and drank it all, then spoke happily.

“………Hmm…………..Eat slowly.”

After Snape finished speaking, he stood up and left the hall, apparently returning to his office.

Kaisen quickly cleared the remaining food on the table and returned to his office. He leaned on the sofa, threw a music record into the record player, and was about to listen to music while resting on the sofa.

Then a figure appeared in front of him. Cedric stood beside him and looked at him blankly, not knowing whether he should greet Kaisen or go home.

But soon the honest Cedric chose to turn around and leave.

"Hey, what are you doing? Are you just here for a stroll and leaving?" Kaisen said with his slightly narrowed eyes.

"Um, Professor, I've already thrown my name into the Goblet of Fire." Cedric walked back and said.

"That's great, so what?" Kaisen stood up and said.

Cedric dug into his pockets. "Here, I wrote to my father a while ago, and this is his reply. He agreed to the alchemical transformation as long as it didn't affect my appearance. It even has his signature on it."

Kaisen took the letter and read it through: "Oh...you couldn't have forged it." Kaisen glanced at Cedric.

"Absolutely not. I'm not the Weasley twins. Besides, my father's magic is on it. It's in the signature and throughout the letter."

Cedric said with a solemn vow.

"Oh, you should have told me about such a big thing in advance, or at least let us meet. It's hard for me to believe that you just brought a piece of letter." Kaisen said with a smack of his lips.

"Professor, you can't synchronize the parent-child relationship in the Muggle worldview with the wizard worldview. In fact, the parent-child relationship in the wizarding world is... much more abstract. As long as it doesn't involve souls and death, young wizards have a very high degree of freedom." Cedric explained.

"Oh, I don't have any children either, so you can't blame me." Kaisen said with a pout.

"Then, professor, do you agree?"

"I want to write a letter to Mr. Diggory myself." Kaisen took out a piece of letter paper and wrote a letter in a few seconds. Then he put it into an envelope together with the reply letter that Cedric took out and mailed it to Mr. Diggory.

Perhaps the owl was surprisingly helpful this time, and Kaisen received a reply in the evening. The content of the letter was as follows...he still agreed.

"Well, your father is quite open-minded." Kaisen put the reply letter into the bookshelf and said to Cedric.

The latter just nodded, sat down on the sofa early, put his hands on his knees, and listened to the instructions obediently.

"I've already taught you about the principles of robotic arms, so I won't waste any more time talking to you. Let's get straight to the point. I will supply you with unlimited knowledge and raw materials, as long as you can learn and make them yourself." The tiny blocks in Kaisen's hands circulated and slowly assembled into the most basic raw materials.

Cedric was about to take action, but was pulled back by Kaisen by the collar.

“Draw a sketch first.”

Cedric reacted quickly: "Okay, okay, I'll draw it right away!" He quickly picked up the quill and parchment, and quickly drew the rough outline of a robotic arm on the coffee table.

A four-jointed robotic arm with a blade at the end.

Kaisen took a look and shook his head. "There are too few joints. This is your first robotic arm, so you can only install it in the center. Otherwise, your body's center of gravity will shift."

"What about you, Professor?" Cedric asked.

“My robotic arm is 50/50 and they are installed together.”

"Is that so..." Cedric nodded. "Then can I just make two robotic arms and install them together?"

"Yes, but it will hurt," Kaisen warned.

"It's okay, I'm not afraid!" Cedric said and started designing the second version.

Soon, another sketch was drawn. There were two robotic arms, one with eight joints, and the other also with eight joints. The ends of the two robotic arms were carefully designed, with one side having a small-caliber cannon centered on a double blade.

On the other side there is also a small caliber cannon in the center of the double blades.

"Two identical ones, not bad. When you make them, remember to make the two robotic arms completely standardized. Otherwise, if one is heavy and the other is light, our balanced design will be wasted." Kaisen said as he took out the materials for Cedric, which were large chunks of mithril, a small amount of iron, and most of the mysterious ingots.

"Professor, why is there so little iron?" Cedric asked.

"The iron is too heavy for your spine to bear."

Cedric nodded, "Good science...and where's your robotic arm, Professor?"

Kaisen sat on the sofa and looked at his current student who wanted to compare himself with him in everything, and felt a strange kind of... joy?

After all, no one doesn't want their students to be excellent, and he is no exception.

"I've strengthened my entire skeleton. Your spine isn't strong enough."

"Professor, I want one too!"

"............Okay." Kaisen gave a weird smile.

He then rummaged through the bookshelf and soon found the design he had used to make the skeleton template for himself and gave it to Cedric.

"This is the design of my original skeleton. If you want to make it, you need to go to Madam Pomfrey first to quickly develop your bones to the limit until the sutures close. Believe me, you don't want to continue to develop your bones after you have already installed the skeleton upgrade."

Feeling burning, a little hot

Chapter 268 Surveillance! Where? Toilet!

"What would happen then?" Cedric asked.

"Your bones are not as strong as the additional bones, but the growth of bones will be more abstract. The additional bones will destroy your original body perception, so that your bones will not stop growing after being compressed, but will... break, just like a hydraulic press pressing a bone vertically." Kaisen explained.

"Oh... wow..." Cedric thought about the scene for a moment. Perhaps his bones were compressed like a telescopic pipe, but he soon realized that his bones were hard, so it would only be... one bone breaking diagonally...

"Professor, I think I need to go to Madam Pomfrey." Cedric said with a wince.

"Then go quickly, the sooner you go, the sooner you'll be back."

Cedric nodded and was about to row out of the office. On the way, he happened to meet Lupin who was also rowing.
